NGINX 503 error followed by repeated error in syslog


Recommended Posts

Hi all, I know the NGINX 503 error has been talked about in the forum however, my case doesn't seem to fit the existing posts.

When I try to login to my UNRAID GUI, I get the NGINX 503 error but a couple of refreshes allows me to login.

However, when I open my syslog, I see this error repeated every 2 seconds.

The offending IP is my windows machine. Can you please advise?

There is something on that windows machine that is making repeated calls to the server. You need to find it and stop it :) 


PROPFIND is somehow related to webdav, if that helps.

Apologies for the delay in responding.

Do you have any tips on how I might find what's making the calls from my windows machine?

Thank you. I don't have any webdavs setup from my unraid server.

Hi Lamp!


did you find it in the end? I am facing exactly the same problem now. Can't find that is doing this

It was something from my desktop hammering the login. Iirc at the time it was a word doc I was editing off the NAS and the auto save was probably going nuts. It's typically some process in the background that's to blame. Hope that helps. If you're having a really hard time, try to shut down the computer and login via phone. (Not ideal, I know)
